Regarding the Gods

First, there was nothing. Then something happened, and energy exploded into the void that existed before our world. This energy and material went on to form stars, planets, galaxies, all the things in the universe. There was another kind of energy released, the energy that makes up the soul. As the bits of energy and material accreted to form planets, so too did this soul energy clump together, and gain consciousness.
These new beings spread through the universe, drifting aimlessly over countless millions of years. Some discovered life growing on planets and were fascinated by these things. They had the same energy they did, but tiny, minuscule amounts, bound to fleshy bodies. The reached out to these early beings, curious. The new beings were frightened, and named the energy beings Gods, and worshiped them to avoid their wrath. The wrath of the gods was accidental at the start. They were still forming minds of their own, and didn't mean to cause floods or for the sky to light on fire.
But the more time the gods spent learning about the humans, the more their own minds were shaped. They liked these fragile mortal creatures, and they liked the praise. And to their surprise, the humans that liked them back shared their tiny bits of soul energy with them once their flesh died. The praise of mortals gave the gods power. This realization changed everything.
Now the gods had reason to compete. Each wanted all the mortals to like them. So they showered the mortals with gifts, loaned them tiny bits of their own soul energy to make them more powerful. Mortals too fought for their gods, each claiming their patron deity was superior. They used their god-given powers against other groups of mortals, and the patron gods of those mortals retaliated. Mortals died by the thousands and so too did their gods, shattered, their energy taken by their conquerors.
This cycle of violence repeated itself over and over. The technological progress of mortals was reset again and again with each god-driven apocalypse, until one final, cataclysmic battle. The nations of mortals were shattered. The gods were exhausted, sick of fighting. A coalition formed, one begging for peace. The other gods listened, though it took centuries for a treaty to be agreed upon.
It was decided that not only would each god have their own group of humans to tend to without interference, they would each also govern one area of influence over the mortals, as to not compete for like minded individuals. Atira, who always tried to preserve mortal lives, officially became the Goddess of Healing. Long had she taught the healing arts, but now she alone would rule that area and her followers would be able to heal wounds with a single touch. Arapys, who was always hungering for a fight, became the God of Blood. His followers were mercenaries, the only mortals to be gifted increased fighting abilities.
They could not rely on themselves to police this treaty, there were too many grudges, too many hurt feelings to be fair to each other. So from the scrapes and fragments of the gods who had fallen in the war, a new god was formed. Each god of the treaty also gave up a sliver of their own power to show their commitment to the peace, and Benorn, God of Broken Promises was born. He chose this name for himself, and declared he would hunt down any who broke their promise to the other gods to keep the peace. He required that all gods, regardless of past friendships, could be called into arms to take down a renegade, and that any who resisted upholding the peace would also be branded a traitor.
The treaty and the promise of peace allowed the mortals to finally rebuild. Cities sprang up in the territories of the gods, and the followers got creative with the powers their gods gave them. In the city of the God of Tailors they created magnificent cloth imbued with different spells that allowed the wearer to appear glamorous, or to disappear from view. They traded with the city of the God of the Forge, whose weapons never dulled. Specializations grew and trade all hinged on the god the goods came from. It was a prosperous time.
But not all the gods had forgotten the past wars. As the mortals flourished, borders were established and rules put in place to regulate trade and resources. Some gods chafed at the restrictions and in secret meetings alliances are forming. Other groups form to counter the rumours of war mongers, made up of gods who would do anything, even break the peace, to defend their people. A third faction also arises, those committed to keeping the treaty at all costs. Tension rises, though mortals are mostly unaware. Only time will tell if the treaty will hold.
